摘要:

盐胁迫是主要的非生物胁迫之一,严重威胁小麦的生长发育,而且小麦耐盐性是一个复杂的数量性状,是由多基因协同控制的,这些基因直接或间接参与离子积累和排斥、氧化还原反应和特定渗透调节物质的积累。了解小麦耐盐基因的研究现状,有利于科学、高效地选育耐盐品种。本文从盐胁迫下耐盐基因调控渗透调节、离子平衡、ROS稳态、激素调节4个方面阐述作物的耐盐性,综述了耐盐基因在小麦适应盐胁迫过程中的作用,为小麦复杂的耐受盐胁迫的机制研究奠定基础。利用现代分子生物学手段挖掘耐盐基因资源并将其导入小麦,是获得高产优质耐盐小麦品种的有效途径。研究与耐盐胁迫相关的基因,对阐明应对盐胁迫的分子机制和途径具有重要作用,对培育具有耐盐胁迫能力的优异种质和研发小麦耐盐栽培技术具有重要的指导意义。

Abstract:

Salt stress stands as one of the primary abiotic stresses severely endangering the growth and development of wheat. Salt tolerance in wheat represents a complex quantitative trait governed by multiple genes. These genes directly or indirectly engage in processes such as ion accumulation and exclusion, redox reactions, and the accumulation of specific osmoregulatory substances. Comprehending the current research landscape of salt-tolerant genes in wheat is conducive to the scientific and efficient breeding of salt-tolerant varieties. This article expounds on crop salt tolerance from four aspects: osmotic regulation, ion balance, ROS homeostasis, and hormone regulation mediated by salt-tolerant genes under salt stress. It summarizes the function of salt-tolerant genes in wheat’‍s adaptation to salt stress, laying the groundwork for investigating the intricate mechanisms of wheat salt tolerance. Therefore, employing modern molecular biology techniques to explore salt-tolerant gene resources and introduce them into wheat is an effective approach to obtain high-yield, high-quality, and salt-tolerant wheat varieties. Research on genes associated with salt-stress tolerance plays a crucial role in elucidating the molecular mechanisms and pathways for dealing with salt stress. It offers significant guidance for cultivating outstanding germplasm with salt-stress tolerance and developing salt-tolerant cultivation techniques for wheat.
